FAIT Internet Software GmbH - - Vienna, AT

DevOps Engineer

This new professional challenge arose from the WunderBaren (wonderful) collaboration with Robert Wunderer.
As a DevOps Engineer I fulfill the following 2 main tasks.

Building a new cloud infrastructure
I am responsible for the planning/architecture and implementation of the new cloud infrastructure.
On the one hand, I am able to incorporate my accumulated experience in cloud technologies and, on the other hand, I have the opportunity to look at, try out and use new technologies for optimal implementation.

Support of the old infrastructure
In addition I also manage the maintenance of the old software infrastructure.
My tasks include ...
  • the monitoring and maintenance of all software components and servers.
  • the communication with the development team regarding the coordination of new software releases.
  • the collaboration with the development team regarding the analysis and resolution of reported software problems.
  • the migration of all necessary data and software components into the new cloud infrastructure.

Collaboration with Robert Wunderer (capriSys)

Creation of a WunderBaren (wonderful) collaboration with Robert Wunderer.

Robert Wunderer's expertise in the area of DevOps was already of great value at TEKAEF. Out of this professional and friendly commitment, the idea of supporting each other in the future was born.

November 2006 - August 2021
ACP TEKAEF GmbH - - Ried im Innkreis/Hohenzell, Upper Austria, AT

IT All-Rounder

In my 15 years at TEKAEF, as an IT all-rounder I was entrusted with the following tasks.

2020 - 2021: E-Commerce Project Manager
The in-house development of the shop software was replaced by another shop system. In this project, I accompanied the migration from the old to the new system until the new shop went live.

2017 - 2020: Development, Team & Project Manager
As main person responsible for the in-house development of a procurement software solution I was assigned with development, team & project management tasks.
I was allowed to independently put together my team of software developers. So within a short time we were a powerful 7-person team. We were able to develop numerous features in only 3 years using the latest cloud technologies. Not only our colleagues and partners, but also our customers were thrilled about this achievement.

2006 - 2017: E-Commerce, Web & Windows Software Developer
At the beginning of this long-lasting partner and friendship I was appointed to the in-house development of a new shop software, which I was able to complete enough in just 1.5 years to replace an old PHP/MySQL shop system.
In this (short) time I managed to recreate all the features and go live with a significantly improved version of the old shop system. Over the course of the following years, the new solution was continually expanded (with functionalities and designs) and adapted to the requirements of the TEKAEF Group and its customers.

Alongside, I was also responsible for the development of numerous websites, landing pages and small Windows apps.

All of this was implemented for the following companies and brands of the TEKAEF Group and their partners:
  • TEKAEF, BÜROLeben, T-MediaGroup, MediaCard
  • Printberry, MAPE, MAPE4You, MAPE Distribution, B2B INK, Company Shopping
  • HP (Hewlett-Packard), HERMA, etc.

2006 - 2016: IT Technician
In addition to my engagement as a software developer, one of my duties was also the representative support of the entire IT landscape (network, server, ERP system, etc.) of the TEKAEF Group.

Enovativ Internet & Multimedia - Ried im Innkreis, Upper Austria, AT

Web Software Developer & IT Technician

Development of a variety of different Internet apps and web pages.

While programming these applications, I was also occupied with the design tasks. Although I was able to add a lot to the design myself by using Photoshop, my task was rather the smooth implementation of the screen designs into the finished Internet application (web page). Here, of course, the close collaboration and communication with the graphic artists/designers was crucial for the smooth process up to the go-live.

IT Technician
My areas of responsibility also included looking after the company network and the Internet servers.

Technologies used
Microsoft Visual Studio .NET (ASP .NET, C# & .NET Framework), HTML/CSS, JavaScript, PHP, Microsoft-SQL-Server, Microsoft-Access, MySQL, XML, Adobe Photoshop, Windows XP & Server

Segue Software Development GmbH (Borland) - - Linz, Upper Austria, AT & Boston, MA, USA

Web Software Developer & Technical Product Documentation

Training and self-study of the Segue software products - SilkPerformer, SilkVision, SilkRadar, etc.
Planning, design and programming of an intranet website, which was also used as an internal communication platform.
Technical Product Documentation (in English) of various products (mainly SilkPerformer).

Intranet Website
During the planning phase of the intranet website, various content management systems were also considered. However, after thorough evaluation, an in-house development was preferred.

The following functionalities were developed for the intranet - news corner, product build information system, department areas, food ordering, computer management, process check list, organizational chart (organizational structure, employee information, telephone lists, etc.), product Palette, document management, search engine (AltaVista), photo gallery (company events), administration functionalities, etc.
The existing Java classes of the web products (SilkVision, SilkRadar), which were adapted and expanded for intranet development, served as a template for the Java part of the intranet.

Technical Product Documentation
The technical documentation of the various software products (mainly SilkPerformer) required precise technical know-how of the products themselves. Moreover, the communication with the developers also played a very important role. The only language used was English, although the developers' documentation was primarily written in German.

The documentation was generated in the following formats - online help (HTML), book form (PDF), context-sensitive help and various other formats (Word, Excel, etc.).

Technologies used
Java, Microsoft-ASP, XML, HTML/CSS, JavaScript, Microsoft-SQL
RoboHelp, Adobe FrameMaker & Acrobat

March 1999 - August 2000
Fabasoft Gruppe - - Linz, Upper Austria, AT

Web Software Developer

Training and self-study of the Fabasoft software product - Fabasoft-Components.
Development of the following 3 web projects.

Fabasoft-Components Web Client
Development of a Fabasoft-Components web client, which should contain the complete functionality of the Fabasoft-Components 32bit Windows client. Microsoft IE, Netscape and Opera (as an alternative) were used as Internet browsers. The web client communicated with Fabasoft-Components via COM interfaces and was implemented using Microsoft-ASP, HTML and JavaScript.
WEB-DAV technology was also used for editing and locking objects used in Fabasoft-Components. An IIS filter and an IIS server extension were developed for this purpose, which served as interfaces between Fabasoft-Components and WEB-DAV.

This web app was offered to customers as a product by Fabasoft.

Fabasoft Website
Complete functional and partly graphical design of the Fabasoft website.

Fabasoft-Components was used as storage and synchronization medium for this homepage. Through this, the high-frequency updates of the HTML pages should be carried out as easily, quickly and cost-effectively as possible. Some functionalities were developed using Microsoft-ASP, HTML and Fabasoft-Components web apps.
Many HTML pages were created using Active Reports, a tool developed in Fabasoft-Components for the dynamic generation of HTML files based on JavaScript and VBScript.

VAPP - Fabasoft Professional Services
Development of a VAPP (virtual application or web application) for the Fabasoft professional services (support, consulting, etc.).

The basic functionality of this was partially reused from the Fabasoft website. It was intended to replace an old web app and thus make it easier and quicker to access for Fabasoft partners.
VAPP is an interface (COM component) developed in Fabasoft-Components which is used to dynamically display objects out of Fabasoft-Components on the Internet. This COM component generates HTML from the objects, which is then transported to the client via IIS. The presentation could be changed via CSS. Here too, as with the web client, WEB-DAV was used.

At that time, all of Fabasoft's Internet projects were implemented with the help of the VAPP technology.

Technologies used
Microsoft-ASP, HTML/CSS, JavaScript, VBScript, Web-DAV, COM-Schnittstellen, Microsoft-SQL-Server, Oracle, Informix, Seagate Crystal Reports, Microsoft-IIS, Windows 2000 & Linux
